RuntimeBrowser is a class browser for the Objective-C runtime on iOS and OS X that exposes all loaded classes, methods, and dynamically generated header files. The companion iOS-Runtime-Headers repo hosts the resulting runtime-derived Objective-C headers for each iOS version.

Use cases

• browse all Objective-C classes loaded in the iOS runtime
• inspect private framework classes and methods on an iPhone
• generate and diff Objective-C headers across iOS versions
• search private API headers for classes or selectors
• dynamically load frameworks and invoke methods at runtime
• explore undocumented iOS APIs before using them

When to choose

• you need to discover or document private Objective-C APIs on iOS or OS X
• you want to compare framework interfaces between iOS releases
• you're doing security research or reverse engineering of Apple frameworks

When to avoid

• you need Swift runtime introspection rather than Objective-C
• you want a supported tool for shipping apps using private APIs
• you need actively maintained tooling with recent updates
